INTAKE SENSOR
Description
INFOID:0000000009950985
COMPONENT DESCRIPTION
• Intake sensor (1) is located on the evaporator.
• The intake sensor converts the evaporator surface temperature
detected with thermistor into the voltage, and the A/C auto amp.
inputs this voltage.
INTAKE TEMPERATURE CORRECTION
• The A/C auto amp. inputs the temperature detected with the intake sensor as the evaporator surface tem-
perature.
• Perform the correction of the temperature detected with the intake sensor for air conditioner control.
• The A/C auto amp. performs the correction so that the recognition intake temperature changes depending
on the difference between the detected intake temperature and the recognition intake temperature. If the dif-
ference is large, the changing is early. The changing becomes slow as the difference becomes small.
Diagnosis Procedure
INFOID:0000000009950986
1.
CHECK INTAKE SENSOR POWER SUPPLY CIRCUIT
1.
Turn the ignition switch OFF.
2.
Disconnect the intake sensor connector.
3.
Turn the ignition switch ON.
4.
Check voltage between intake sensor harness connector and the ground.
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> GO TO 4.
2.
CHECK INTAKE SENSOR GROUND CIRCUIT CONTINUITY
1.
Turn the ignition switch OFF.
2.
Disconnect the A/C auto amp. connector.
3.
Check continuity between intake sensor harness connector and A/C auto amp. harness connector.
Is the inspection result normal?
YES
>> GO TO 3.
NO
>> Repair the harnesses or connectors.
3.
CHECK INTAKE SENSOR
Check the intake sensor components. Refer to
HAC-40, "Component Inspection"
Is the inspection result normal?

SUNLOAD SENSOR
Description
INFOID:0000000009950988
COMPONENT DESCRIPTION
• The sunload sensor (1) is installed to the right side of instrument
panel assembly.
• The sunload sensor converts the sunload amount (illuminance)
into the current value with the photodiode. The A/C auto amp. cal-
culates this current value to the voltage and inputs it.
SUNLOAD AMOUNT CORRECTION
• The A/C auto amp. inputs the sunload amount detected with the sunload sensor.
• Perform the correction of the sunload amount detected with the sunload sensor for each air conditioner con-
trol.
• When the sunload amount suddenly changes, for example when entering a tunnel, perform the correction so
that the recognition sunload amount of the A/C auto amp. changes slowly.
Diagnosis Procedure
INFOID:0000000009950989
1.
CHECK SUNLOAD SENSOR POWER SUPPLY CIRCUIT
1.
Turn the ignition switch OFF.
2.
Disconnect the sunload sensor connector.
3.
Turn the ignition switch ON.
4.
Check voltage between sunload sensor harness connector and the ground.
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> GO TO 4.
2.
CHECK SUNLOAD SENSOR GROUND CIRCUIT CONTINUITY
1.
Turn the ignition switch OFF.
2.
Disconnect the A/C auto amp. connector.
3.
Check continuity between sunload sensor harness connector and A/C auto amp. harness connector.
Is the inspection result normal?
YES
>> GO TO 3.
NO
>> Repair the harnesses or connectors.
3.
CHECK SUNLOAD SENSOR
1.
Connect the sunload sensor connector.
2.
Connect the A/C auto amp. connector.
3.
Check the sunload sensor components. Refer to
HAC-42, "Component Inspection"
